If you haven't already drawn the straight line between climate change and the evolution/spread of new diseases, please pick up your pens now. Don't limit this to human infection. All species risk infection as we fuck up the planet (see little brown bats).
On a human scale, there is noplace that safe from the effects of ebola outbreaks, novel virus strains, etc. and as disease vectors, we are pretty damned good at spreading sickness all over the place - by ship, plane, train, car, and through aerosol and contact.
On the more observable side of weather events, wind and ice storms are occurring inland with higher intensity and frequency, and outpacing our municipal, provincial, and federal budgets. A 100 year storm means our budgets are prepared to fix that damage once every 100 years. With the frequency of these storms increasing, our budgets cannot keep up. Note tax increases through COVID and in the next 20 years - our already crumbling infrastructure is now seeing weather event loading beyond its original design.
Invasive species are upsetting the "normal" ecosystem as warming occurs (see "Dog Strangling Vine"). The change in temperature is affecting us already and upsetting crops and aquifers worldwide. This is a fight that is at a tipping point already, and to be honest, has been for some time.
There is no hidden to the time bomb. It is already going off, we just aren't willing to admit it.
